Which of the ordered pairs
(0, 0), (�2, 10), (�1, �5), (�3, 9)
are solutions for the equation y = 5x?
:
This is so easy. You know that the 1st digit in the pair is x and the 2nd is y:
:
y = 5x
Substitute the value of x for x and see if it equals y
:
(0,0)
y = 5*0
y = 0 so this is a solution:
:
(-2,10)
y = 5*-2
y = -10; this is not a solution
:
(-1,-5)
y = 5*-1
y = -5; this is a solution
:
(-3,9)
y = 5*-3
y = -15; this is not a solution

Do you understand this now? Any questions?
